Background: Traditionally, several external approaches are used to treat the maxillary sinus tumors, especially for the malignant tumors. However, open approaches for resection of maxillary sinus tumors is associated with increased morbidity, such as facial scar and so on.

Objective: In this study, we evaluate our early experience with endoscopic partial maxillectomy for the maxillary sinus tumors.

Methodology: A retrospective analysis of 12 patients undergoing endoscopic partial maxillectomy between 2017 and 2018 was undertaken. The data of patients’ demographics, clinical features, and treatment outcomes were recorded and analyzed.

Results: A total of 12 patients with primary maxillary sinus tumors were reviewed and consisted of 7 females and 5 males. All patients underwent endoscopic partial maxillectomy. Endoscopic anterior transmaxillary approach was completed in 5 patients, and transnasal endoscopic resection in seven patients. The follow-up period ranged between 1 and 1.5 years. There is no recurrence in all patients until now. Postoperative pathology demonstrated that adenoid cystic carcinoma was detected in 5 patients, melanoma in 2 patents, chondrosarcoma in 1 patient, fibrosarcoma in 1 patient, papilloma in 2 patients, inverted papilloma with malignant transformation in 1 patient.

Conclusion: Our experience indicates that the endoscopic partial maxillectomy with transnasal approach and/or transmaxillary approach for the maxillary sinus tumors is safe and effective. However, more cases and a longer follow-up are needed to confirm its long-term outcome.
